Reason for revert:
Setting the BAD_BUILDS_CHECK env variable should
be enough. Lets revert this as the code doesn't
look particularly good. There must be another
problem still that needs investigation.

This patch provides improved infrastructure for developing test262 tests
together with V8. It has three parts:
- The test262 test runner is updated to look for local versions of tests
in the /test/test262/local-tests directory, which mirrors
/test/test262/data. Additional tests can be added there and are run
together with tests from upstream. Upstream tests can be locally
updated by using the same name in local-tests; if a same-named test
exists, then only the local version will be run. The local-tests
directory is in the V8 repository, unlike the contents of the data
directory, so tests can be added in the same patch as something else.
- The tool /test/test262/upstream-local-tests.sh is added to create
a patch against the test262 respository based on a patch which changes
the local-tests directory.
- The tool /test/test262/prune-local-tests.sh is added to remove
redundant local tests on a test262 roll.

Our test infrastructure ignores missing tests which are listed in
status files. Sometimes, tests are removed and status file lines
are not updated. This patch adds a presubmit check for status
files addressing JavaScript tests to not reference missing tests.
It also cleans up existing violations.

For benchmarks with multiple measurements (e.g. runtime, compile

last portion of the name ("Compile"), which is ambiguous and makes
debugging dificult. This change includes the full name, e.g.

If a key is a substring of an earlier value, then the earlier value
will unintentionally be clobbered. For example with:
macro SET_PRIVATE(obj, sym, val) = (obj[sym] = val);
SET_PRIVATE(iterator, arrayIteratorObjectSymbol, object);
if the mapping is:
{'val': 'object',
'obj': 'iterator',
'sym': 'arrayIteratorObjectSymbol'}
then 'obj' -> 'iterator' will clobber 'val' -> 'object', resulting in
'val' -> 'iteratorect'. To fix this, replace all substitutions
simultaneously.

This makes test outcomes immutable. This has two benefits:
1) It's more robust. Using the |= operator by mistake
wouldn't lead to unwanted mutation.
2) It's faster as now the set reference can be copied again
when copying test cases. Test case copying happens an order
of magnitude more often than rules do apply.

This adds the possibility to address test cases in the
status file with the variant under which the test is running.
This is only allowed in top-level sections.
Example:
[{
'test-case': [PASS, SLOW],
}]
['variant == foo', {
'test-case': [FAIL],
}]
The test case "test-case" is marked as slow in all variants.
Additionally, in variant foo, it'll be expected to fail.
This CL also exemplifies the new feature with test cases
running under the ignition_turbofan variant. The
corresponding legacy flag is deprecated.

perf-turbo.py merges a perf data file and a turbofan trace file into a
single json object which can then be piped to a file and uploaded to
turbolizer to display the profiling data in the disassembly. With the
changes, turbolizer now shows the event counts for instruction in
percentage form and with heatmap-stype colouring. Multiple different
events can be recorded at once with a new drop-down menu to select which
event to view the counts of. The documentation has been updated with
instructions. Using the script is optional and turbolizer retains
previous functionality if a trace without profiling data is uploaded.

With this patch, every node in turbo-*.json has an opcode, a title, and
a label. The label field is new; the opcode and title were already
there. The title is for the mouseover text. The label is what will be
displayed in the graph view, unless it's too long, in which case only
the opcode will be displayed. (This is similar to the preexisting
behaviour of putting titles in labels, except that the titles were
rarely short enough to fit in a label.)
With this patch, the labels generated are in practice the same as the
titles we had before, except for LoadField and StoreField, which will be
rendered as LoadField[[+432]] and StoreField[[+432]] (if 432 was the
offset).
This diff adds an overloadable method
virtual void Operator1<T>::PrintParameter(ostream&, PrintVerbosity)
for each type T to Operator1. Its default implementation just uses
operator<<(ostream&, T const&) and adds square brackets around it, but
it is overridden for FieldAccess to print "[+432]" in the example case.

This change analyzes and links the output of --code-comments in the disassembly view within turbolizer with the other views, such that selecting these comments will also select the respective blocks/lines/nodes within the other views. The block start comments (e.g. -- B4 start --) are linked with the blocks in the schedule phase view and vice versa. The source position comments (e.g. -- primes.js:3:10 --) select the respective spans, lines, and nodes in the JavaScript code view, the schedule phase view, and the other compilation phase views respectively, and vice versa. It also modifies the display of the line and column numbers in the source position comments to be offset from 1 instead of 0 and ignore the initial source position of the first line of code (from removal of the function name in the compiler).
Also fixed the bug where previous selections weren't being cleared properly across multiple views, adding appropriate clear calls when using the selection broker.
